Tiny correctness fix.
What changed
`kiss_matcher.version` is now derived from the installed package
metadata (`importlib.metadata.version("kiss_matcher")`) instead of a
hardcoded string. v1.0.0 and v1.0.1 both reported `version == "1.0.0"`
at runtime regardless of the actual installed version; v1.0.2 fixes that
drift and any future bump is reflected automatically.
No API changes
Same wheels, same coverage as v1.0.1.
